PIPE-CLAMP. A

Specification of Letters Patent. Patentgd June 8, 1915.

Application filed July 11, 1913. Serial No. 778,526.

To all whom it may concern:

Be it known that I, ANDREW H. CALD-' has for its object a clamp capable of holding a plurality of pipes of different sizes, which clamp is particularly simple in construction, economical in manufacture and highly eificient in use; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is an elevation of my pipe clamp with a pipe therein. Fig. 2 is a plan of the pipe clamp, the jaws being open. Fig. 3 is a transverse section through the clamp with the jaws closed, a pipe being shown therein.

This pipe clamp comprises a main jaw having concave working faces of different radii, and a plurality of jaws each having a working face complemental to one of the working faces of the main jaw.

The working faces of the main jaw are in the form of cylindrically concave channels arranged end to end and with their axes at an obtuse angle to each other so that when the pipe is held in the working face of larger radii it can pass beyond the working face of less radii, as seen in Fig. 1.

1 is the main jaw which consists of sections 2, 3 rigidly secured together and usually formed integral, the sections being arranged at an obtuse angle to each other.

4 and 5 are the cylindrically concave channels in the faces of the jaws, these channels being of different radii and running into each other at their contiguous ends and the axes of such channels being arranged at an obtuse angle to each other so that the channel of smaller diameter is thrown out of the way of the pipe in the channel of larger diameter.

6 and 7 are the jaws having channels 8 and 9 complemental to the channels 4: and 5 respectively. The jaws 6 and 7 being hinged at 10 to the main jaw. The channels are faced with a suitable material 11 designed to engage the pipe and prevent marring thereof, and the margins of such material lap over onto ledges 12 formed in the edges of the jaws.

- The channels 4, 5 and 8, 9 are designed to hold pipes of different diameter, as for instance, a" pipe and 9 pipe and owing to the fact that the sections of the main jaw are arranged at an angle to each other the a" pipe, when held in position can project beyond the section of the main jaw having a" working faces.

The clamp is usually made to hold two pipes, and the channels are made to fit two sizes of pipe which are usually used together on certain classes of work, as for instance basin and bath supply pipes are in two sizes 3- and and one form of my pipe clamp is applicable tothese sizes of pipes. Hence a plumber, when going out on a job can select the pipe clamp he will need and will not have to carry a number of such pipe clamps.

What I claim is:

1. A pipe clamp including a main jaw formed with an angle therein between its ends, the working faces thereof on opposite sides of the angle being of difl'erent radii, and movable jaws coacting with the portions of the main jaw on opposite sides of its angle, substantially as and for the purpose described.

2. A pipe clamp comprising a main jaw having concave working faces of difi'erent radii for fitting different sizes of pipes, the

working faces being arranged with their axes at an obtuse angle to each other, and jaws for coacting with the main jaw, each of the latter jaws having a working face complemental to one of the working faces of the main jaw, substantially as and for the purpose specified.

3. A pipe clamp comprising a main jaw including sections rigidly connected together and arranged end to end at an obtuse angle, the sections being formed with lengthwise channels opening into each other, the channels being concave and of different radii and arranged with their axes at an obtuse angle to each other, and a jaw for each section of the main jaw, each of the of Jefi'erson, in the State of New York, this latter hai ling a chmnel complemental 10th day of June, 1913. r V V to one 0 t e c annels 0 the main 'aW substantially as and for the purpose sei; foi'th.
